IGM Omnirad 907 UV Photoinitiator

IGM Omnirad 907 is a high-efficiency alpha-amino ketone Type I free radical UV photoinitiator in the Omnirad series, designed for UV radiation curing systems. Its core component is 2-Methyl-1-(4-(methylthio)phenyl)-2-morpholino-propan-1-one. It can efficiently decompose to generate free radicals under UV light, quickly initiating the photopolymerization of unsaturated prepolymers such as acrylates with mono and multifunctional vinyl monomers
